Hydrofluoro alcohols of formula : A-(R f ) a -CFX-O-R h O-(CFX-(R f ) a* -CFX-O-R h O-) n H (I) in which : R h is a hydrocarbon-based chain; X is F or a C 1 -C 6 (per)fluoroalkyl; a or a* is 0 or 1; R f is a (per)fluoro(poly)oxyalkylene chain or a (per)fluoroalkyl chain; A is chosen from -F, -C1 and -H (possible only when a = 1) or is HO- R h -O-CFX-; n is an integer from 0 to 200, with the condition that n = 0 when A is chosen from -F, -C1 and -H. |
